Description

I attempted to extract ANSI art packs from SixteenColors ANSI archive but many of them fail.

 

Upon some debugging it appears that as many of the file names contain ANSI characters which are parsed by the ArchiveInputStream as question marks, the file fails to be saved to disk as question mark is a bad character to be had in a filename.

Specific code:

ArchiveInputStream archiveInputStream = archiveStreamFactory.createArchiveInputStream(ArchiveStreamFactory.ZIP, inputStream);
ArchiveEntry archiveEntry = null;
while((archiveEntry = archiveInputStream.getNextEntry()) != null) {
Path path = Paths.get(extractDirectory, archiveEntry.getName());

example of a non parseable filename in an archive:
